Describe your change:

Adds the clear_least_significant_set_bit() function to bit_manipulation/single_bit_manipulation_operations.py.
This function efficiently clears the rightmost set bit using the bitwise operation: number & (number - 1).

Includes comprehensive doctests with 5 test cases covering various scenarios including edge cases (zero input, single bit).

Fixes #12970
